[2,2'-(Ethylenedioxy)dibenzaldehyde bis(thiosemicarbazone)]nickel(II) diperchlorate methanol disolvate
X.-H.. Qiu and H.-Y. Wu
Abstract: The title compound, [Ni(C18H18N6O2S2)](ClO4)2·2CH4O, (I), has been prepared by the reaction of 2,2'-(ethylenedioxy)dibenzaldehyde bis(thiosemicarbazone), L, with nickel(II) perchlorate. The chemical structural unit, which is twice the asymmetric unit of (I), consists of one NiII ion, one ligand L, two methanol solvent molecules and two uncoordinated perchlorate anions. The Ni atom lies on a crystallographic twofold axis of rotation. The ligand L coordinates to the central Ni atom through two O atoms, two S atoms and two N atoms, giving a distorted octahedral environment. The S and O atoms occupy equatorial positions, and are nearly coplanar with the nickel, while the two N atoms occupy axial positions, with the N-Ni-N angle being 177.06 (18)°.
